The 5-1/2 digit Model 6487 Picoammeter/Voltage Source improves on
the measurement capability of the award-winning Model 6485, and adds a high
resolution 500V source. It provides higher accuracy and faster rise times than
the 6485, as well as a damping function for use with capacitive devices. With
eight current measurement ranges and high speed autoranging, this
cost-effective instrument can measure currents from 20fA to 20mA, take
measurements at speeds up to 1000 readings per second, and source voltage from
200μV to 505V.
